Angular position sensor

Abstract

The invention relates to an angular position sensor for determining a relative angular position in relation to a reference position, comprising a housing (1), at least one rotor (3, 4) that is rotatably mounted in the housing (1), and a printed circuit board (2) that has electric and / or electronic components and one or more stators, corresponding to the number of rotors (3, 4). A connecting component (7) prevents the housing (1) from being twisted in a groove of a stationary part of a motor vehicle. The aim is to improve said angular position sensor in such a way as to avoid play under any operating conditions when preventing the housing from being twisted and make it easy to mount the sensor. In order to be able to do so, a plastic spring (13) of the connecting component (7) is supported by a metal spring (14).

Description

technical field

[0001] The invention relates to an angle-of-rotation sensor for determining a relative angular position with respect to a reference position, said angle-of-rotation sensor comprising a housing, at least one rotor rotatably mounted in the housing, and a printed circuit board, the printed circuit The plate has electrical and / or electronic components and one or more stators corresponding to the number of rotors, and the housing is prevented from turning in recesses of the fastening part of the motor vehicle by means of connecting elements. Background technique

[0002] Such inductive torque sensors are known per se. They are used, for example, in motor vehicles to determine torques, such as steering torques. This is becoming more and more necessary as electric servos are increasingly used to assist steering. The servo requires steering torque for control. The steering torque can be detected in the steering column via the torsion bar as an angular difference a...
